Definitions
- the invention relates to an arrangement for the isolated coupling of electrically conductive components, in particular in gas-insulated switchgear, comprising a first electrically conductive component and a second electrically conductive component, wherein the components are separated from each other by a flexible insulating.
- FIG. 4 of DE 199 40 634 A1 shows two insulated conductors, which are electrically conductively connected to one another by a contact ring.
- the contact ring serves as a coupling.
- an elongated tube made of an elastic insulating material is placed.
- the insulating layer thickness of the insulating material increases, its flexibility decreases, which in particular has a detrimental effect on the insulation of connectors.
- gas-insulated switchgear In the medium-voltage and high-voltage range, gas-insulated switchgear is used, in which various plug connections are realized. From the prior art it is particularly known to use cable connectors or component couplers for connectors. This connection technique was adopted from the medium voltage technology.
- the invention is therefore an object of the invention to provide a problem-free isolated connection of components, especially in complex gas-insulated switchgear, with an insulation should be available, which remains highly flexible even with increasing strength and in particular to allow eversion or shifting.
- the above object is achieved by an arrangement with the features of claim 1. Furthermore, the invention relates to an insulating element and the use of the arrangement for connecting components in high-voltage switchgear.
- the insulating member consists of a stable flexible shell which is filled with an insulating agent.
- the insulating means can be formed from a liquid, gel-like and / or solid material, for example silicone oil or silicone gel of high viscosity, and the flexible sheath can be designed as a flexible thin silicone sheath.
- the flexibility of the insulating is adjustable in many areas and the thin outer skin of the insulating is largely flexible.
- This construction makes it possible to shape these with thick insulating layers and to adapt or invert the contours.
- the preferred embodiments of the insulating element are pillow-shaped, tubular, annular, spherical and / or conical.
- a further embodiment of the invention relates to the connection of components in gas-insulated switchgear comprising a first housing part and a second housing part, wherein in the first housing part, a first insulated conductor is received, wherein in the second housing part, a second insulated conductor is accommodated and wherein the insulated conductors via connecting means electrically conductively connected to each other.
- an insulating element that is electrically insulating, at least partially removable, is provided for this purpose, which is flexibly deformable in such a way that it can be turned over.
- the connecting means comprise several parts.
- the parts can be designed as rails or half shells.
- the insulating element is advantageously set with one end premounted on a housing part such that its other end can be transferred to the other housing part.
- the insulating element can thus remain captive after disassembly on a housing part.
- the insulating is easily umstülpbar or rolled up. It can be unrolled from one housing part and rolled up on another.
- the first housing part receives a first insulating body which receives the first insulated conductor and electrically insulated from the first housing part.
- the insulating is easily umstülpbar or rolled up. It can be unrolled from a housing part and rolled up on another such that it rests against it and / or on the insulating body assigned to it.
- the second housing part receives a second insulating body, which receives the second insulated conductor and electrically insulated from the second housing part.
- the insulating is easily umstülpbar or rolled up. It can be unrolled from a housing part and rolled up on another such that it rests against it and / or on the insulating body assigned to it.
- the insulating element is fixed by a respective clamping device on the first insulating body and on the second insulating body. The clamping devices can exert a radially acting compressive force on the insulating element and prevent a gap formation at the boundary surfaces between the insulating bodies and the insulating element.
- the insulating element at its two ends in each case a collar.
- the collar forms a trough in which the clamping devices are accommodated.
- the clamping devices are thereby secured against axial displacement to the outside.
- the insulating element is made of several layers.
- the insulating element may consist of several controlled layers in order to obtain the flexibility required for its everting.
- the insulating element is provided in certain areas with a conductive layer for field control.
- the first housing part and / or the second housing part is or are received gas-tight in the wall of a gas space, wherein the first insulated conductor or the second insulated conductor protrudes into the gas space or is electrically connected to electrical components within the gas space.
- connection point An insulation of the connection point can be carried out with an insulating liquid or insulating gas. For this purpose, however, a tight housing must be provided around the connection point.
- the arrangement described above is advantageously used for the isolated coupling of electrically conductive components in gas-insulated switchgear and can be used in all areas of high voltage engineering in which single-phase insulators are used. Only the thickness of an insulating section must be adapted to the respective physical and structural conditions. In particular, the flexibility mentioned must be taken into account.
- connection technology also facilitates the dismantling of components, in particular of field components. Furthermore, it enables compact constructions, which are characterized by a very high ease of installation. Due to their design, the connecting means can accommodate greater tolerances, which makes possible new concepts for switchgear.
